Hydatidiform mole

Published on 24 November 2020

The hydatidiform mole service provides diagnosis and follow-up support for women with a molar pregnancy. This occurs when abnormal cells grow inside the womb rather than a baby. The service is in the Department of Blood Sciences at Ninewells Hospital, Dundee.

What support does the hydatidiform mole service provide?

If it’s suspected that a woman has a hydatidiform mole, a referral is made to the service to confirm the diagnosis. If the test result is positive, the patient is enrolled in the laboratory follow-up programme. This allows for early identification of the signs of persistent trophoblastic disease (PTD) or the development of choriocarcinoma. PTD happens when some molar tissue is left behind following treatment, while choriocarcinoma is a uterine cancer.

A positive test result will result in the patient being referred to Charing Cross Hospital in London where chemotherapy treatment can begin. The Dundee team coordinates this care and provides ongoing follow-up support.
